  How key-based cache expiration works

There are only two hard things in Computer Science: cache invalidation and naming things — Phil Karlton Doing cache invalidation by hand is an incredibly frustrating and error-prone process. You’re very likely to forget a spot and let stale data get served. That’s enough to turn most people off russian-doll caching structures, like the one we’re using for Basecamp Next. Thankfully there’s a better way. A much better way. It’s called key-based cac...

  Binary tree iterator algorithm

Binary tree pre-order,in-order and post-order traversal are basics in algorithm and data structure.And the recursive binary tree traversal is a classical application of recursion. We define a binary tree node as : // C++ struct Node { int value; Node *left; Node *right; } In order binary tree traversal can be: // C++ void inorder_traverse(Node *node) { if (NULL != node->left) { inorder_traverse(node->left); } do_something(node); if (NULL != node->righ...

  JavaScript-style object literals in PHP

The object literal notation in JavaScript looks like: var fido = {name: "Fido", barks: true}; or var fido = {}; fido.name = "Fido"; fido.barks = true; From assoc arrays to objects In PHP you would call that an associative array. $fido = array( 'name' => "Fido", 'barks' => true ); And you can easily make it an object too: $fido = (object)$fido; echo gettype($fido); // "object" Or if you want to start with a blank object and add stuff to it: $fido = (object)array(); or $fido...

  Java Concurrency Basics: CountDownLatch and CyclicBarrier

CountDownLatch CountDownLatch can be used in synchronizing behavior among threads, it makes one or more threads wait for some actions in other threads to be completed. It has a property count which defines how many countDown() need to be called before other threads which called await() to be waked up.  When a thread calls CountDownLatch.await(), the thread will be blocked until the value of count becomes 0. The initial value of count can be specified when creating the CountDownLatch instanc...

  A simple tutorial on writing Java native program

Java provides Java Native Interface(JNI) to enable developers to write programs which can utilize the underlying native libraries of the operating system. The benefits of writing native code are that they normally provide better performance compared to Java codes. Sometimes if you want to utilize some system specific functions you may also want to use JNI. One main drawback of writing native code is that your application may not be platform independent anymore. This is not what Java is desi...
